2008 MBP destroying power adapters... possible?

Hey there,
My partner has a MBP ( 2.4Ghz 2GB RAM ) from 2008 which has recently managed to get through 3 AC adapters.
The chargers don't show any sign of intermittent failure, they just work and then.. don't!
Two of these were official Apple adapters, and the 3rd was an unofficial replacement from eBay. All three have broken within about 2 weeks (although the original Apple one was a year or so old).
The chargers are also getting very very hot, not just warm.
Could this be a problem with the actual Macbook internals or is it just bad luck with chargers? The MBP charges fine and draws/holds the power as it should, but I don't know enough about the workings of a computer or electronics to know whether it is actually possible that the MacBook is in some way damaging the chargers.
Many thanks

I would say that the problem is in the MacBook. It's drawing to much current for some reason.

My power socket destroys MagSafe power adapters?

I don't have the slightest clue how, but one of my MagSafe power adapters for my MacBook Pro just failed completely, and didn't work with my other MBP and on another socket. So I said to myself "Ok, I'll get another one from Apple since its under warenty" and plugged another MagSafe into the same socket, and plugged it in and it charged my computer all the way. This one i got to watch die. The green LED flashed a couple of times, and then went dead. I've done all the troubleshooting, and nothing works. Two questions: What can I do to fix this? And do you think its my socket? It never destroyed my Klipsh speakers. I need this for work, and a dead battery isn't going to cut it. BTW, I have installed 10.6.8, even though my product list doesn't say so.

They should be able to work that out for you and put your mind at ease. Good luck to you.

Foreign power adapters on US MBP?

I'm planning on buying a MacBook Pro in a few months, but I'll be moving from the US to the UK in September and was wondering if a MacBook Pro power adapter bought from Apple UK would be safe to use with my American MBP. I know that the world travel adapter kit would work, but I don't necessarily want to add anymore bulk to the power brick, which I hear is quite large. I was looking at the manual online and it says to only use the power adapter that came with the MBP, but if that was true than why are extra power adapters sold at all?
Thanks.

I can tell you for a fact that you won't have any problems. I use the US power supply in Europe and all I need is the adaptor to make the US plug into the local socket. As an additional option, I am sure that there will be a UK power supply if you don't want the hasle of using an adaptor.

HI! early 2008 MBP 4,1 startup or power up Failure! HELP! thks!

I have an early 2008 Macbook pro 4,1. The computer was sleeping all night, and when I pull up the screen to use it, the Mac apparently was running but no screen on it, so I try to increase or decrease de light on the screen but nothing happened, so I force it to shut down with the power bottom, then I tried to power it up, and it really does for 2 to 3 seconds, and it shut down... there is nothing at screen. What i did to troubleshoot with no results: press de power bottom for 5 seconds with no mega safe adapter and battery - press de left shift + option + command + power bottom with the megasafe adapter - I did take the HDD - took de RAM memory.
Another thing: When I took the Ram memory the MB stayed beeping like telling me that there was no memory, but it didn’t shut down. I had to shut it down myself...
Any suggestion please!? Thanks a lot!

The early 2008 MBPs had serious videocard problems which you may be experiencing. You will need to go to an Apple Store or service provider to have the MBP tested which may cost you. The problem is that the 4 year extended video card warranty has long expired for all these models so getting a free repair is not likely.

Which OS, Version, Best Setup on like-new 2008 MBP for non-HD archival DV?

MacBook Pro 15"
(Early 2008)
2.4 GHz Core 2 Duo
4GB RAM
720GB 7200rpm Hard Drive (original 360GB 5400rpm drive also available)
OS 10.6.8
(6GB RAM possible but additional $100+ for 4GB module needed now for software upgrades)
    I first and last used Final Cut Pro 2-3 in film school on a Titanium PowerBook (500MHz!) during the OS9/X transition. Next, was an Aluminum PowerBook (1.67Ghz) but because of life changes, I did little editing other than occasionally in iMovie. Then as an early adopter of iPhone/Pad, I rarely used my AlPB other than for back up, writing, and occasional simple editing.
    Now I'm finally entering the early MacIntel age with a pristine "early 2008" MacBook Pro bought for $250 from an elderly original-owner couple who used it only at home for email and iPhoto. Though at the end of its supported life, it's practically new with a known history of light graphics usage (no video or gaming rendering ever) delivered in the original box with original battery (only 46 cycles!), discs, manual, like-new charger, and no sign of wear. The original internal wrapper was even saved and put back on the device! Furthermore, because the wife was a photo enthusiast, the Apple Store swapped out her internal hard drive for a Western Digital 720GB 7200rpm drive and the husband just gave me the original 360GB drive!
    I want to do several things with this "new" device. I've done a lot of research but the world has changed since FCP 3 and the G4 processor and I'm overwhelmed with all the possibilities. I need guidance and have always appreciated the wisdom and generosity of the gurus here. I thank you all in advance!
iCloud integration: I'd like it since I'm an iPhone/Pad user. I could upgrade to Mountain Lion but Mavericks, under the best of conditions, is doable on my device and may give me improved CPU and battery performance. I realize this is best left for the OSX forums. HOWEVER...
Final Cut Pro: I want to also return to editing in FCP an unfinished documentary using primarily archival film and video converted to non-HD DV. This may greatly impact how I set up my drives and the decision as to which OS is best. So, this should probably be my initial decision.
Hard Drive: First and foremost, I should probably swap the drives and place the 7200rpm drive into an enclosure (Firewire or is that stone-age?) for FCP media, correct?
OS: With Mavericks, I must use FCPX which is beyond my current non-HD needs and will most likely strain my system resources. However, the new simplified interface is appealing and I've read some users are running it on "early 2008" MBPs. If an earlier OS is better suited, then which one? And also...
FCP Version: Which is most stable given my model? And which is best for non-HD needs? What about FCExpress? I want to explore more possibilities than what's available in iMovie and would appreciate the simpler interface found in FCE and FCPX, especially since I haven't used any Final Cut since FCP 3 but will gladly embrace what's best. I want to relearn the program and hope to continue using it for other projects.
Partitioned drive: Finally, what about partitioning my drive, one for daily life running Mavericks or other OS, the other solely dedicated to an optimized OS/FCP for non-HD editing? Even at 360 GB it should be doable if I keep it lean and the bulk of storage externally (I ran FCP 3 adequately on a partitioned 40GB drive back in the day). How much space should I dedicate to an FCP partition?
    Finances are tight and I'll need to upgrade Office, other apps (I know there's Rosetta in Snow Leopard but must weigh that with iCloud integration; decsions, decisions!) and probably locate an older copy of FCP on EBay or elsewhere which could be expensive. I must wait a bit before swapping in a 4GB RAM module and possibly upgrading to an SSD. Meanwhile, I'd like to experience this like-new MacBook Pro now, both as it was during its heyday and with what's still possible today. It seems doable and I appreciate any and all suggestions.
Thank you all and have a great day!
Evalyn
PS: I realize my FCP3 files are probably useless and plan to reimport everything into a new project. And sorry for the lack of paragraph spacing. Can't get it formatted right on the iPad!

Just to note that there is much more commonality between FCP3 and FCP7 and/or FCE than with the early version and FCP X. IMO, learning FCP X is worth the effort, but it will require some effort since it is so different than traditional NLE's. You could "get by" with FCE for many types of projects and you should be able to find a copy on eBay or Amazon for a few hundred dollars. However, you will not be able to open a FCP project of any version with it. Also, I don;t think I would agree that its UI is simple; it's essentially the same as FCP.
As for partitioning, some people advise against editing from drives that have been partitioned. I use a partition on one machine and I've not had any problems, so I think it is an option.
As you can see from the replies you've received so far, you have reasonable choices. Good luck.

2 Power adapters...one glows amber to charge the other stays green??

Hello,
I have 2 power adapters for my ibook, the one that came with it originally & one I bought as an extra. They are both 45W apple ones. I have had problems with my ibook powering up & after replacing the dc-in board to no avail I have been told it's the logic board that needs replacing.
I have just got a replacement logic board which I am yet to fit. As it stands at the moment I have replaced the dc-in board but still won't charge the battery?
Also when I use the adapter that came with my ibook the light on the adapter glows green. When I plug the extra adapter in it glows amber but doesnt charge the battery?
I am just confused as to why one adapter glows green & the other glows amber with the same battery in?
I am also concerned to know if it would have been possible for the replacement adapter to have caused the logic board failure in the first place? As I am replacing the logic board soon I don't want the same mistake to happen again!
Anyone help??

All-right Master Meister, one last throw of the dice for me...
Do you have a friend or relative who knows how to use a multi-meter? If so, get them to check the voltage + current flow from the adapters when connected to the mains (iBook unattached).
Please do not try this yourself if you are unfamiliar with multi-meters; you could electrocute yourself or irreparably damage your equipment.
If you are reasonably competent with basic electronics, hook up a 12V car battery to one side of the charger and a 3V torch (with batteries removed) to the other side. If the bulb lights, this will tell you if the adapter is working.
I mean no disrespect: this is a potentially dangerous experiment and if you don't feel you are up to it, then don't try.
Instead, take the adapters to your local electronics store and pay them to check them for you.

Understanding iPhone Charging and Power Adapters

I've been in a protracted discussion (now locked) regarding iPhone battery charging and whether it is harmful/helpful to use the iPad power adapter rather than the iPhone power adapter.
There are a lot of misconceptions related to iPhone charging and current ratings on the iPhone and iPad power adapters. As an electrical engineer, I'd like to clear up some misconceptions.
Apple supplies a power adapter, not a "battery charger," with the iPhone and iPad.
The iPhone power adapter supplies a constant 5V at up to 1A (rated–independent tests have shown that it can supply almost 1.8A).
The iPad power adapter supplies a constant 5V at up to 2 or 2.1A (rated).
The iPhone's battery charging voltage and current are regulated within the phone.
The iPhone's battery is rated at 3.7V. Charged with the raw 5V from the power adapter, it would be destroyed. Fortunately, the internal regulation in the iPhone prevents that.
The maximum current that an iPhone will draw from a 5V power adapter is right around 1 amp. It does not matter if the charger is capable of supplying more, that's the most that the iPhone will use.
Because of the internal charge regulation, the iPhone battery will not charge any faster on an iPad power adapter than on an iPhone power adapter.
Apple approves the use of the iPad power adapter with the iPhone. It is completely safe for that purpose and does not harm the phone or battery in any way.
A water analogy might make this much easier for people without electrical engineering background to understand.
Water pressure (psi) is analogous to voltage.
Water flow (gallons per minute) is equivalent to current flow (amps).
A faucet valve is analogous to the iPhones battery charging regulation circuitry.
A bucket's capacity (gallons) is analogous to a battery's capacity (amp-hours or AH).
Let's say you adjust the faucet to flow 1/10 of a gallon per hour. The five gallon bucket will take 50 minutes to fill up. Easy enough. But then...
You need a lot more water flow for a new sprinkler system.
You need a lot more current for your new iPad.
Since the water pressure is constant at 80psi, the only way to get more flow use a bigger supply line.
Since the voltage is constant at 5V, the only way to get more current is to use a higher current power adapter.
After installing the new higher capacity water supply line, you go out to your faucet and adjust it to 1/10 of a gallon per hour.
After plugging in the higher capacity iPad adapter, you plug in your iPhone and its charging regulation circuitry adjusts the current flow to about an amp.
The bucket still takes just as long to fill up.
The battery still takes just as long to charge.
The faucet is not under additional strain since the pressure is still 80psi.
The iPhone's battery charging circuitry is not under additional strain since the supply voltage is still 5V.
I hope that I've clarified this for those who want to better understand the subject.

As far as the battery status, the tiny little icon in
the upper right corner of the screen is somewhat
helpful, but while it is connected it does not
actually indicate the level of the charge or that the
Iphone is charging. I was hoping to find a more
informative screen that would give better battery
details. When you first connect the iPhone sometimes
I get a large battery icon that shows the level
visually Is there a way to navigate to this screen?
1. Press the top button to turn the display off if it's not off already.
2. Connect to a power source.
3. The screen should display a large battery meter in the middle of the screen that actually shows the state of charge, even if charging.
If you don't see this plugged into your Mac try the AC adapter that came with the phone. If you still don't see it take it to an Apple store.
best,

SSD Upgrade to Late 2008 MBP, Plus Windows 8 Install

Hi guys,
I have a 15", late 2008 MBP that was a beast in it's time, but has started to show it's age, especially due to my aging hard drive. I've read great things about performance improvement through installing an SSD, and so I want to perform this upgrade. Also, while I do have my computer backed up through Time Machine, I'd rather just be proactive on replacing my hard drive before it fails on me (which will definitely happen at some point). Here's some more detailed specs for my computer:
CPU: 2.66 GHz Intel Core 2 Duo
RAM: 4 GB of 1067 MHz DDR 3
GPU: NVIDIA GeForce 9600M GT 512 MB
Note about the GPU: This comp has the dual graphics chips, but I've been always using the "high-performance" one, which is what is listed above (the other one is a GeForce 9400M).
OS: Most current version of Mavericks (OSX 10.9.2)
In looking up SSD's, I've found that people that have had laptops with similar specs to mine have had success with the Crucial M500 SSDs.
After I get my drive all figured out, I want to use Boot Camp to install Windows 8 on the SSD. Currently, I do not have any Windows installations on my computer. My computer is not supported for Windows 8 installation through Boot Camp, despite the fact that hardware-wise, it is compatable with Windows 8. However, I have found discussions that are pretty standard on how to get Windows 8 installed on my computer.
-So, my first question is: Was my research good for this given SSD for my computer? It seems like Samsung makes the best SSDs, but I haven't found any evidence that it would be really compatable with my computer.
-My second question: Given that I will have just installed an SSD, will Windows 8 installation be doable? This is probably the most important question for me, because if it's not possible, then I'd rather just buy Windows 7 right off the bat and install that in boot camp instead.
-My third question: If I can get Windows up and running, how does my computer's double graphics chip configuration work in Windows? I'd want to make sure that Windows is using the more powerful of the chips and not the less powerful one.
-My fourth question: My computer has gone from Leopard to Snow Leopard to Mavericks, and I never performed a "clean install" for any of these OS upgrades. If I clone my HD to the SSD, would it be beneficial for me to run a Mavericks clean install, and then pull all my necessary data off my backup drive?
Sorry for the long-winded post, and I know much of it is demonstrated elsewhere. I have found many discussions involving SSD upgrades, and getting Windows 8 on a late 2008 MBP, but I haven't found anything that has shown both being done. Both seem easy to do, but I just don't know if doing both in tandem is going to cause a bunch of problems. Has anyone out there done this, and can anyone offer me any advice on how to make this process any smoother? I really like doing this upgrade now, because if I run into Windows issues, or other issues on the SSD, I could still just boot from my old hard drive and use my computer. Thanks everyone!

beestmode,
I have a Mid 2010 MacBook Pro, and I put a Samsung 840 PRO SSD into mine. Where did you find evidence that this model SSD would not work in your MacBook Pro? (The SSD which you’ve installed has a good reputation, so you should have no reason to regret your choice.)
Windows 8 via Boot Camp will not be possible with your model MacBook Pro. In Boot Camp, you could install up to Windows 7, either 32-bit or 64-bit. A virtualizer such as Parallels Desktop or VirtualBox could allow you to install Windows 8, but virtualizers have their own sets of positives and negatives.
Since I have a 13-inch model with only one GPU, I don’t know how your dual GPUs would be handled on the Windows side.
When I’d installed my SSD, I did a clean installation of Mavericks onto it, keeping Snow Leopard on my old internal disk, and putting it into an external enclosure.

2008 MBP -- DVI out -- DVI/HDMI converter -- HDTV ?

Hi guys,
I'm gonna go ahead and apologize in advance if this has been asked before, I'm having a bit of an emergency.
The backlight on my 2008 MBP (model A1260) has gone out -- I can still somewhat see the screen but it's extremely dim. I'm wondering if I can buy a DVI/HDMI converter and run the video out to my HDTV. Are there any extra supplies I'll need?
Also, any instructions for enabling the HDTV as my external display would be greatly appreciated as I'm barely able to read anything on the screen in its current state.
Thanks so much!

MacBook and MacBook Pro power adapters cross compatible?

Greetings~!
I have a MBP, and I just bought my girlfriend a MacBook for her B-Day.
I realize there is a wattage difference between the two power adapters. The MBP is 85watts and the MB is 60watts.
So... to me, I could use the 85watt power adapter to charge the MacBook... but not the other way around.
Has anyone experienced using any other power adapter with the MacBook?

I'm sorry I can't find the reference article for this but I remember reading that as long as the batteries are present you are fine either way, noting that the MBP hooked to a 60 W supply will take a little longer to charge than you are used to with the 85. However, I'm pretty sure it also said you could see problems in the unlikely scenario that you had the 60 W connected to a MBP with no battery present. In that case the MBP would be asking for up to 85 but only getting 60. I don't know enough about it to be able to say that would actually be a problem.

Power adapters interchangeable?

My wife and I have a 17" MBP and a 13" MBP. We use the power adapters interchangeably--it's even hard to determine which is which.
Of course, the 13 uses a 60 Watt Power Adapter and the 17 uses a 85 Watt. Any problems with this?

Here's the skinny. If you have the computer under heavy load then it draws the needed extra power from the battery. If you were to remove the battery and run from the AC adaptor alone then the CPU's clock speed is throttled back to reduce the power demand to what is supportable on the AC adaptor alone.
Since rechargeable batteries require a level of current at the charging voltage, if the charger cannot supply the current then the battery may not charge completely or will take a longer time to charge.

90w vs. 65w power adapters

We use the T61's and X61's with the port replicators for the T's and the Ultrabases for the X's. Is there any reason or need for the 90w power supplies? Please advse. Thank you.

Hello,
Welcome to the forums.
The difference between the 90W and 65W power adapters is quite simply the power output to the computer based on power consumption by the unit.
The T-series systems with dedicated video cards (NVidia or ATI) require the more powerful 90W power adapters - the 65W PAs will not provide sufficient power required by the dedicated video cards. Thus the 90W power adaper is the only choice for T-series systems with dedicated video cards.
The X-series, on the other hand, use an on-board graphics adapter without dedicated GPU and come with the 65W power supply simply because of the much lower power requirement. The X-series systems (whether docked in the X6 ultrabase or not), unlike the T-series sibblings, may use either the 90W or the 65W power adapters interchangeably.
Hope that helps

Intego VirusBarrier X6 Probs 2008 MBP

All
I have a 2008 MBP with Lion 10.7.1. Ever since I upgraded to Lion with X6, every time my computer came out of sleep or standby, the MAC would shoot up to 100 CPU and become completely unresponsive for a good 3-5 minutes. Sometimes it would crash (full on Kernal panic) and when it came up it would show the last thread was Intego. Sometimes I'd have to hard boot it to get it work again.
This weekend I erased and completely reinstalled OS X Lion and rebuilt it completely. I left Intego off. For 2 days now problems. Ran great, came out sleep/standby w/o problems of any kind. I downloaded Intego today, put it on, updated it thru Net Update and my problem came back. Go figure. If I shut down Intego completely, the problem goes away.
I wrote Intego and there response every time is to uninstall and reinstall. Worthless!
Is anyone else have these problems on a 2008 MBP?
I have to say Intego's customer service is horrible and so far, their product is too.

@Jeff26 - I have X6 set up for LOW priority for CPU and disk operations and it only scans once a week on Monday's at 9AM. It's set up to not count files before a scan and overall it's very, very basic in the settings. I did that on purpose since malware and viruses are not as prevelent on a MAC. But like I stated if you shut it completely off, problem goes away. And I have very little actually running on this MAC. I use it mainly for web surfing and picture editing with Aperture and I only open Aperture when I need to. 90% of the time it's web surfing which isn't a tax on the CPU.
It's possible a setting I have is causing it, but getting anyone from that company to work with you beside "uninstall/Reinstall" is like pulling teeth. And the manual ***** and so do their forums. I'm stumped.
I have read a few other web posts of people with the same MBP as me having the same problems and since I didn't have it on SL and I do on Lion, I'm betting the problem is with this Intel Core2Duo vs. the new i7's and how Lion runs thru the kernals.
@Allen - I agree, but we still have to be careful with viruses and malware on MAC's. It's only a matter of time before they start coming out of the woodwork.

Do Apple MagSafe 2 power adapters break easily?

I was about to order a Magsafe 2 power adapter for my rMBP so I could keep one at home and one at work. But there are hundreds of reviews at store.apple.com saying they break easily, the wires fray, etc. but I've seen very few complaints about them on this or other user forums, and none of the five I've owned for various MacBooks since 2010 have ever broke.
Are Macbook power adapters really so unreliable and prone to breaking? Or is it possible that the reviews at Store.apple.com are so dominated by trolls as to be unreliable?

People don't often write reviews about things as mundane as power adapters unless they have something to complain about. I have one that's only recently started to fray. It's four years old. I have many others as old, or older, and they're fine. Treat them carefully and they ought to last the life of your Mac.
